Screw earring clamp with spring to prevent loosening

ABSTRACT

A SCREW TYPE EARRING CLAMP PROVIDING IMPROVED GRIP WHEREIN A THUMB SCREW IS TIGHTENED TO MOVE TOWARD THE EAR LOBE FLANGE TO PUSH AGAINST THE EAR LOBE AND, IN TURN, THE EAR LOBE CONTACTS THE POST OF THE EARRING CLAMP WHICH, IN TURN, HOLDS THE EARRING TO THE EAR LOBE, THE DEVICE IS OF SIMPLE CONSTRUCTION AND PROVIDES EASE OF ADJUSTMENT FOR APPLYING DIFFERENTIAL PRESSURE WITH RESPECT TO THE THREADED SUPPORT MEMBERS OF THE EARRING CLAMP.

The present invention represents an improvement over the conventional screw type earring clamp, and more particularly it relates to apparatus and means for securing the earring onto the ear lobe.

A unique advantage of the present invention is that the clamp is comfortable to wear because the spring tension is only sufficient to hold the clamp onto the ear lobe, and adjustment of the screw tension is made on the wire spring for maintaining the correct tension at all times.

Another advantage of the invention is that there is no means by which the elements may jam or become disassembled, as in the prior art devices such as found in Marcus 2,417,117.

A further object and simple concept of the invention is that the earring is merely a thin wire spring that can be manufactured with simplicity and economically and does not change the design, appearance and neatness of the earring. The tension spring is integrated into the design and structure of the earring and clamp.

The above and other objects and advantages of the invention will become apparent upon full consideration of the following detailed description and accompanying drawings in which:

FIG. 1 is an elevation view of the tight-grip screw arrangement of the earring clamp; and

FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. 1.

Referring now to the drawings, there is shown an earring ill having a bracket or yoke 12 from which there is connected at the distal or outer end 14- an ornament mem ber 16 in which there is disposed intermediate the length ends of the yoke 12 a pendant means 18. At the other end or the yoke 12, there is a threaded aperture M in which there is threadedly engaged therein a screw 25 having a thumb wheel 3t) for turning the screw 26, and on the other end of the screw there is a rotatably mounted ace member 35 1- to engage with a lobe of the ear. Thus the face member and the engaging portion of member 16 clamp upon and engage with the ear lobe.

in order to secure the threaded members 241, 26 from moving with respect to each other, there is a spring clamp provided to urge the threaded member as into a tight relation with the threaded aperture 24, so that the threaded member 2.6 does not move after it has been set and turned by the thumb wheel Ml. The spring clamp provides a tight grip upon the screw, and at its fixed end it is securely connected and fastened upon the intermediate portion of the yoke 12, as shown.

Additional embodiments of the invention in this specification will occur to others and therefore it is intended that the scope of the invention be limited only by the appended claim and not by the embodiment described hereinanove, Accordingly, reference should be made to the following claim in determining the full scope of the invention.

What is claimed is:

1. An earring clamp having a thin yoke member with an ornamental member at one end, a thumb screw engaging a threaded aperture at the other end of said yoke, said other end having substantially the same thinness as the rest of the yoke, said thumb screw having a thumb wheel fixed at its end outward of said yoke and a rela tively rotatably mounted tace member at its inward end, a thin, relatively narrow spring member securely fixed to an intermediate portion of said yoke, the free end of said spring member having a vertical longitudinal slot therein through which the shaft of said thumb screw passes, said free end being in pressure contact with the inner surface of the thumb wheel of said thumb screw, said slot being of a size and shape permitting vertical movement trans verse relative to the longitudinal axis of said thumb screw, said free end pressing said thumb screw in a direction out from said aperture as said thumb screw is turned thereby preventing any play or loosening between the threads of said aperture and said thumb screw once said thumb screw is set.
